Check all the valve to valve measurements on the seat on each chamber. Note the chamber with the closest measurement, pull that piston/rod out and mock up the head/actual valvetrain on that cylinder. See that you have the minimum of .025" as Jeff said at valve overlap. I would leave the intakes alone, and sink/clip the exhausts to get your clearance.

Careful about following the mopar "bible" too much, that info is way outdated.
